Single Pair Ethernet Will Connect IoT Devices

When a new copper or fiber cabling technology is developed, it’s only natural to assume it was designed to carry higher speeds in support of the seemingly endless need for more bandwidth. While that is usually a safe assumption, there are instances where new media types are developed to provide more cost-effective transport for lower speed applications.

Such is the case with the activities around single pair Ethernet applications standards. This is certainly not a new topic, as this technology has been standardized and is in use in the automotive industry and in several industrial applications.

However, with the tremendous growth of the Internet of Things (IoT) and the need to provide cost-effective power, connectivity and security to the billions of edge devices that will be deployed over the next decade, single pair Ethernet has emerged as a very promising technology. Because the bulk of IoT devices being deployed do not require nearly as much bandwidth and power as a typical application using traditional 4-pair cabling, single-pair Ethernet promises to provide a more compact and economical solution.

Ethernet has enjoyed resounding success as it enters its sixth decade, as the opportunity to standardize on one protocol for the data link layer provides great benefit. With the addition of more cost-effective means of connecting IoT devices, its success will continue in the form of single pair Ethernet.
